242 Question.

Chasjr1 · Jul 24, 2015

I'm going to convert my 2000 from a 231 to a 242 for the full time 4wd capability. I have found a transfer case that is marked as a New Venture 242J. Made 12-08-98. It appears this is a compatible match. It will be rebuilt with a sye kit, and freshened up inside.

Can anyone tell me if this is a correct match. I'll gather the shift gate and bezel later.

I could be wrong but IIRC there isn't an SYE made for the 242.

Otherwise, yes the case you found is acceptable.

Tom woods makes a sye, spendy but it's the only non hack n tap one

Chasjr1 · Jul 25, 2015

I thought Tom Woods made one. Either way (Tom Woods or HnT), it will be pretty simple since I'm going to tear it apart and recondition it. Plus I know a machinist. The HnT cutting and threading will be pretty simple.

Make sure the yokes are the same as what's on your 231, if so its a winner

Chasjr1 · Jul 25, 2015

Very cool. Thanks all.

Digger87xj · Jul 27, 2015

Good to know :idea:
Glad I was mistaken

Chasjr1 · Jul 27, 2015

Here's a pic of the tag. Was able to talk them to $150 for it.

The 242 was only used on the XJ, ZJ, and WJ jeeps. If they are from the same era (95-down and 96-up) then they are 99% the same. Worst case you might have to swap the input shaft if the transmission was different, or change a yoke from CV style to u-joint style, or something like that.

That's what I've learned. The tags say '98, my XJ is a 2000. My only major issue now seems to be the rear retainer. My XJ has the VSS there. The donor I bought has a place for it, but isn't machined out (plus IDK if the output shaft has the gear cut). I'm pretty sure I can get these issues taken care of.

The sye will replace the rear cone and should have provisions for a speedo gear.

All XJs had the speedo output in the transfer case, so yours is from a ZJ or WJ

What is stamped on the red tag? I have a parts unit that says 242-WJ

As Digger said, you will replace the tail housing anyway

Digger87xj · Jul 28, 2015

It's out of a WJ. The ZJ was no longer in production when that thing was built.

ehall · Jul 28, 2015

Good point, dec 98 is for 99 model

Chasjr1 · Jul 28, 2015

Yes. It appears to be off a WJ. So now, it appears I'll need to find an XJ rear retainer if I just swap it across for now. Or have it machined. The main reason for the SYE was for a future lift.

ehall · Jul 28, 2015

The one from your 231 may bolt on. Count the bolts and check the pattern. You would need to remove the slinger, rear output seal, couple of snap rings

Does that 242-WJ have a u-joint yoke for the front output? Mine has a CV yoke

Chasjr1 · Jul 28, 2015

The one off the 231 won't fit. I've checked it. And the front output is a CV type. It seems I've got some parts to collect.

Just remembered, you'll probably need to change the shifter tab on the 242-WJ, since its setup for inverse throw.

Thanks for the tip. You answered a question I've been wondering about since looking through my MY 2000 Parts Catalog and seeing a different tab than the one on my TC.

ehall · Aug 2, 2015

For the tab, you should really look into buying the Boostwerks linkage, it really simplifies things down there. You won't need another tab either, since the kit comes with one. http://www.boostwerksengineering.com/242-HD-Shift-Linkage-Auto-Trans-_p_27.html

The indicator switch on your 242-WJ is different from the one that is used with the XJ. You will need to replace that, and you will also need to find the jumper sub-harness for your year--might be able to get to get one from the dealer otherwise you'll have to find an XJ 242 in the junkyard or in a part-out.

Also I just swapped the 242-WJ differential into my XJ case (old-style main shaft) and a couple of other parts, everything went over fine
